This invention relates to siphon heads or appliances for deliveringaerated or gaseous liquids from bottles containing the same, the objectbeing chiefly to construct a siphon head which secures durability andabsence of leakage, even with high pressure, and also to prevent thecontact of the liquid with metal.

In the accompanying drawings, Figure 1 is a front elevation of a siphonhead constructed according to our invention. Fig. 2 is a sectional sideview of the head. Fig. 3 shows in section and elevation the arrangementfor openingandshnttingthevalve. Fg.4shows, in vertical sections andplan, the outer casing of the parts of the head. Fig. 5 shows the innercasing of the valve itself in vertical sections and elevation, and Fig.6 is a vertical section of the internal parts of the valve.

As illustrated by the accompanying' drawings the improved Siphon headchiefly comprises a cap B, provided with a lateral discharge pipe B andmade ot' glass, porcelain, stoneware, or other suitable equivalentmaterial; a conical capsule D, of india-rubber over which the cap isplaced, and which in its turn iits over a cone C of porcelain, in thelower cylindrical opening of which is set the ascension pipe R by meansof shellac,wax, or the like, and which is xed upon the usual siphonbottle S having a packing ring G interposed. The whole of the parts areheld together bya stamped, cast or drawn casing A of aluminium, brass,cast iron, steel, or otherl suitable substance, which is screwed ontothe bottle or flask by means ot` the usual screw ring P. In the upperpart of this casing there is a cross shaped slot, through which a leverE with its fulcrum enters a groove or depression in the cap B underneaththe top of the casing.

Between the cap B and the cone C is inserted an india-rubber ring F. Inthe groove or depression g in the head of the capsule B there isinserted a metal plate abouttwo millimeters thick, acting as a regulatoras hereinafter described.

The actual closing parts are,l as shown in the drawings, neitherscrewednor riveted, they mutually support each other and are only moved by theelasticity of the indiarubber and the pressure of the lever and of thewater. In order to obtain an absolutely tight closure which shall actquite surely with every, even the least, pressure of gas and allow of thwithdrawal of the aerated water to the last drop, in almost a completemanner, and at the same time to effect this object with as littlewearing out as possible of the parts themselves the latter may suitablybe arranged as followsz-The cone C Figs. 2 and 6 of porcelain, glass, orearthenware, with its packing ring G, set upon the bottle S, is made upof three cylinders Z Z2, Z3, of successively increasing diameterconically arranged from above downward and of equal height, 13 is incontact with a supported conical piece m which rests upon the plate o,provided with a circular rabbet n, and this plate is continued downwardby a small conical support p. In the inside of the cone O at its lowerpart is a cylindrical socket q for the reception of the ascension pipeR.This socket extends approximately to the middle of the cone, and itstermination limits the entrance of the ascension pipe; from this point asomewhat smaller bore q of a slightly conical form is continued throughthe cone. The conical supportp projects into the mouth of the bottle,and insures the centering of the whole of the closing mechansm withreference to the bottle. The cone piece m serves tosupport the loweredge of the india-rubber cone D, to prevent the latter from coming outwhen the siphon bottle is filled and closed, and it also serves to guidethe the cap B. The plate o with the circular rabbet n serves as a holdfor the incurved portions (more particularly described hereinaffter) ofthe casing A, by means of which portions the cone C is tightly pressedon to the packing ring G, that is to say, on to the bottle.

On the porcelain cone C is drawn the elastic cone D, of white, black orred Para rubber (Figs. 2 and 6) its inner diameter being somewhatsmaller than the outer diameter of the porcelain cone, and its outerdiameter being at the same time in a similar proportion larger than thatof the inner conical hollow in the cap B, tothe extent of about onetenth of a millimeter upon the whole diameter. As is shown in Figs. 2and 6 the india-rubber cone D is also constructed with three steps,inside and out, and tapered off at the edge. In the interior it formsthe graduated hollow receiver for the three cylinders of which the coneC. is made up, but its lowest stage is about one millimeter less inheight than the cylinder Z3 of the cone C which corresponds to it, theobject of this being to afford room for the play of the india-rubberwhen the connection with'the flask is made, and to'A avoid jamming ofthe cone and cap. It is closed above with the exception of a smallhole?n in the center, which corresponds with the upper hollow q of thecone C. The india-rubber cone D cuts off absolutely the connectionbetween the cap B and the cone C and completes the non-metallic passagefor the water between the lower end of the ascension pipe and the outletat the nozzle B.

The space inside the porcelain cap B (Figs. l, 2, 3 and 5) which restsupon the india-rubber cone D is made up of the three cylindrical spacesc', t2, fc3, slightly conical from above downward (Fig. 5). The top ofthe hollow is as shown in Figs. 2, 3 and 5, somewhat convex at tu forthe sake of rapid division of the water, it is moreover furnished with aring shaped depression hwhich is interrupted by the outlet t'corresponding to the nozzlein front. This depression h effects theself-acting opening or retreat of the cap independently of the pressureof gas, and keeps the siphon always open when not in action, whereby theemptying of the lastportion of the contents of the siphon is effected,and'also the india-rubber cone is saved from wearing out too rapidly.The spout B of the cap forms the outlet. Y

The cap is cylindrical outside, rounded above, and provided with thespout B previously mentioned. Its upper part is provided with a groove gin which fits a regulating plate H of brass or any hard metal, thethickness of the plate varying according to the amount of' the cut offand the desired force of the outiiowing stream. This regulating plate Hnot only protects the cap from thc direct pressure of the lowereccentric portion of the lever E and lessens the friction of the latter,but has also the purpose of regulating, when used of differentstrengths, the rate of outflow of the water as well as the degree` ot'tightness of the whole closing mechanism, and also allows theindia-rubber cone when it has been long used to have an efficaciouspressure exerted upon it until it becomes nearl worn out.

On the right and left of the cap are provided rib-shaped projectionsfand f2 which prevent the cap from rotating in the casing A. On theincnrved edge of the latter between the cone C and the cap B isinterposed a ring F of white, black, or red Para rubber of circularsection, the inner smaller diameter of which is somewhat less than themiddle diameter of the cone piecem of the cone. The diameter of itscircular cross section is equal to the distance between the edge of thecap and the incurved portion of the casing. This ring F is intended tocheck the back play of Ithe cap, caused by the action of the cone D andrecess h by itsA elasticity, when the Siphon is opened and in additionto prevent the entrance of dust and dirt between the cone and the cap.All the parts are held together by the previously mentioned casing A(Figs. 1, 2 and 4) of aluminium, brass, or thelike, which casing endsabovein a rounded head, and has its front side cut away nearly to themiddle for the admission of the cap B. On the under part of this openingthe plate which forms the casing is curved inward in a semicircular format CZ and at the same height the plate on the hinder portion ofthecasing is cut through at three or several places and the resulting iapsd', d2, cl3 are curved inward. The edge d and the flaps d', d2, d3, areintended to press the cone C upon the packing ring G and the latteragain upon the neckof the bottle, when the casing A is drawn upon thescrew P, and to draw the cone down thus giving stability to the casingor conevand the wholeapparatus.

An opening E provided in the back part of the head of the casing serves,when the bottle is being filled, to allow of the passage of thesteadying support of the filling apparatus, which might otherwise pressagainst the cap, and so prevents the siphon from receding when themonth-piece of the filling apparatus presses against the spout B. Thelever E (Fig. 3) which has been previously referred to with itscentrally placed eccentric piece t and pins u', u2, passes through across-shaped opening a., b, provided in the upper portion of the head.On t-he inner surface of the head of the casing exactly in the middleare depressed bearings c', c2, which serve to receive the pins u', u2 onwhich the whole lever E moves. The latter is adouble lever of a form sochosen that when mounted in position every time one arm of the levercomes into contact with the casing the movement is limited, and theother arm is ready for open- IIO ing or closing the Siphon. The innercurve of the two arms s', s2, corresponds exactly to that of the outerSurface of the casing. The eccentric piece t (Fig. 3) comes into actionwhen the Siphon is being closed, and presses down the regulating plate Huntil the motion of the lever arm s2 having reached its full extent saideccentric piece t will be situated nearly above the center toward theleft, whereby the return motion of the lever arm which has descended isprevented. The pins u', u2 which rest in the bearings c', c2 inconjunction with the eccentric piece t which moves in the longitudinalslot a effect the accurately firm and straight guiding of the lever inthe-casing. After the separate parts have been properly put together andare irmly connected to the bottle by the operation of the annular screwP, the filling of the siphon bottle may be effected in the usual waybydriving the water in through the spout B', the Siphon bottle beingturned upside down. The closure of the Siphon is then eected by pressingdown the right arm s2 of the lever, whereupon the eccentric presses uponthe bearing plate H, this again presses down the cap B, the curved innerSurface of which is then driven against the openingr in the indiarubbercone D, covers the latter, and thus prevents the outflow; the throw ofthe arm s2 being now at its limit the eccentric piece t stands somewhatlaterally above the vertical line, whereby the closure is insured. Theseveral stages in the india-rubber cone are at the same time pressedfirmly against the internal graduations of the cap B, and the porcelaincone C so that the closure is always absolutely certain, while thepressure exerted by the eccentric and the gas not only acts upon theupper part of the outlet but is distributed over the whole of theindia-rubber cone. The indiarubber ring F is likewise compressed at thesame time by the lower part of the cap. When the Siphon is to be openedthe left lever arm s is pressed down, the eccentric is thereby shiftedto the right, as shown in Fig. 8, and thus permits the retreat of thecap, brought about by the elasticity of D and F, whereupon the annulargroove h in the head of the cap raises the latter automatically from theindia-rubber to a sufficient extent, to allow the proper outflow for thestream of liquid as it issues, this stream being controlled in its forceand speed by the plate H. The path for the issuing water is thus nearlya straight one so that the carbonic acid,which is only mechanicallymixed, is not as in siphons, as heretofore constructed, disengaged bycontact with sharp angles and so on. In its whole course the liquid doesnot come into contact with any metal, which is of considerableimportance from a sanitary and hygienic point of view, the liquid hasalso a more agreeable taste in consequence.

By means of the arrangement described the ordinary Siphon bottles may bemade use of; the closing mechanism may however, without departing fromthe fundamental principle of the invention, be so arranged as that forexample the glass or porcelain cone C may in part be made in one piecewiththe flask, while the upper part carries the ascension pipe, or thatthe cone may be inserted in the widened neck of the flask instead ofbeing set upon the latter. Moreover, the le- `ver arrangement E foropening and closing the Siphon may be replaced by a screw mechanism, andthe casing A may be replaced by a simple stirrup, the lever arrangementabove described, and the casing, are however to be preferred as beingmore advantageous.

Having now particularly described and ascertained the nature of our saidinvention andin'what manner the same is to be performed, we declare thatwhat we claim isz- 1. The combination of a stepped cone adapted to beaffixed to a bottle or the like, a stepped cone shaped sleeve washeradapted to be placed around said cone, an outlet piece having a steppedcone shaped recess placed around the cone shaped washer, and means forcompressing and releasingthe outlet-piece.

2. The combination of a cone C, a cone shaped washer D placed thereon,an outlet piece B having a cone recess placed upon said washer, a casingA, a lever E having bearings in the casing and adapted to compress andrelease said outlet piece.

3. The combination of a Stopper-cone having a series of annular stepsthereon, a flexible cone washer having a series of annular steps thereonfitting over and concentricl with the steps on the stopper, and a capoutlet fitting over said washer, having a valvepiece adapted to engagesaid washer.

4. The combination of a conical stepped Stopper U, a conical steppedwasher fitting over said stopper, a cap outlet having conical steppedsurfaces fitting over said washer and provided with a valve seat andoutlet, and a casing fitting over said cap outlet having a leverjournaled therein at its top provided with a cam.
